| |
Hi,
Current code has below voltage table for ldo19:
static const unsigned int ldo19_voltages[] = { 1800000, 1850000, 1900000, 1750000, 2800000, 2850000, 2900000, 3000000, };
The 1750000 looks unusual but I cannot find the datasheet to confirm it. I found in the initial version of the patch submission, it has below regulator-vset-table [1]
+ ldo19: regulator@a38 { + compatible = "hisilicon,hi655x-regulator-pmic"; + regulator-name = "ldo19"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <3000000>; + regulator-initial-mode = <0x02>; + regulator-off-on-delay = <360>; + regulator-ctrl-regs = <0x02f 0x030 0x031>; + regulator-ctrl-mask = <0x2>; + regulator-vset-regs = <0x084>; + regulator-vset-mask = <0x3>; + regulator-n-vol = <8>; + regulator-vset-table = <1800000>,<1850000>, + <1900000>,<2750000>, + <2800000>,<2850000>, + <2900000>,<3000000>;
So I'm wondering if the 1750000 is a typo? (should be 2750000). Can someone help to confirm this?
